Effectiveness of Individual Exercise and Sport Counseling Based on Motives and Goals: A Randomized Controlled Trial

This study tested the effectiveness of individual exercise and sport counseling in a nonclinical setting. The COunseling based on Motives and goals in Exercise and sporT (COMET) approach focuses on individual motives and goals and aims to identify suitable activities. Participants experience different exercise and sport activities and reflect on them with a counselor, who applies motivational interviewing. A stratified randomized controlled design with 129 people was used. The intervention group took part in a counseling event, which included feedback on motives and goals, trial exercise and sport sessions, and structured reflection. Four weeks later, members of the group got a telephone booster. The control group received minimal intervention as written information. Results show that the counseling promoted motivational competence (eta(2) = .16), physical activity-specific selfcontrol (eta(2) = .08), and the weekly volume of exercise and sport (eta(2) = .15), whereas it did not influence self-concordance. Further studies can investigate whether the COMET approach is also effective in other settings.
